Poinsettia plant named ‘PER6401’

ABSTRACT

A new and distinct cultivar of Poinsettia plant named ‘PER6401’, characterized by its inflorescences with light red-colored flower bracts with random pale yellow-colored flecks; dark green-colored leaves; uniform, compact, upright and mounded plant habit; early season flowering; natural season flower maturity date is late November for plants grown in Encinitas, Calif.; and excellent post-production longevity.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following related application: Poinsettia Plant Named ‘PER5499’ (U.S. Plant patent application Ser. No. 10/955,476), filed concurrently; Ruth Kobayashi, applicant.

Botanical classification/cultivar designation: Euphorbia pulcherrima Willd. cultivar PER6401.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd, and hereinafter referred to by the name ‘PER6401’.

The new Poinsettia a product of a planned breeding program conducted by the Inventor in Encinitas, Calif. The objective of the breeding program is to create new early flowering Poinsettia cultivars having strong stems, attractive flower bract coloration, uniform plant habit and excellent post-production longevity.

The new Poinsettia is a naturally-occurring branch mutation of the Poinsettia cultivar Eckaykin, disclosed in U.S. Plant Pat. No. 13,326. The new Poinsettia was discovered and selected by the Inventor in a controlled environment in Encinitas, Calif. on Dec. 31, 2000. The new Poinsettia was selected on the basis its unique flower bract coloration.

Asexual reproduction of the new Poinsettia by terminal cuttings propagated in a controlled environment in Encinitas, Calif., since February, 2003, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PER6401’. These characteristics in combination distinguish ‘PER6401’ as a new and distinct cultivar:

-   -   1. Inflorescences with light red-colored flower bracts with         random pale yellow-colored flecks.     -   2. Dark green-colored leaves.     -   3. Uniform, compact, upright and mounded plant habit.     -   4. Early season flowering; natural season flower maturity date         is late November for plants grown in Encinitas, Calif.     -   5. Excellent post-production longevity.

Plants of the new Poinsettia are most similar to plants of the parent, the cultivar Eckaykin. Plants of the new Poinsettia differ from plants of the cultivar Eckaykin primarily in flower bract color as plants of the cultivar Eckaykin have red-colored flower bracts with pink flecks.

Plants of the new Poinsettia can be compared to plants of the cultivar PER5499, disclosed in a U.S. Plant patent application Ser. No. 10/955,476 filed concurrently. Plants of the new Poinsettia and the cultivar PER5499 differ primarily in flower bract coloration.

Plants of the new Poinsettia can be compared to plants of the cultivar 127, disclosed in U.S. Plant Pat. No. 7,308. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar 127 in the following characteristics:

-   -   1. Plants of the new Poinsettia were more compact than and not         as vigorous as plants of the cultivar 127.     -   2. Plants of the new Poinsettia flowered about two weeks earlier         than plants of the cultivar 127.     -   3. Plants of the new Poinsettia and the cultivar 127 differed in         flower bract coloration as plants of the cultivar 127 had         red-colored flower bracts with pink flecks.

DETAILED BOTANICAL DESCRIPTION

The new Poinsettia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and averaged measurements describe plants grown in Encinitas, Calif. during the autumn under commercial practice in a polycarbonate-covered greenhouse with day temperatures averaging about 29° C., night temperatures averaging about 19° C. and light levels about 4,000 footcandles. Single plants were grown in 16.5-cm pots and pinched once. Plants were flowered under natural season short day/long night conditions. Plants were about 16.5 weeks from unrooted cuttings when the photographs and the detailed botanical description were taken.
